My girlfriend is studying out of country his summer and I was bored so I decided to have fun with some self bondage. I Inserted my special friend  ;-p and put on my sluttiest purple panties to help keep it in, and proceeded to tie a shibari harness on myself.  I put on my  leather posture collar, and decided to bind my ankles with rope which I affixed to the harness in a hog tie. I the turned the vibe on and did something very silly. I handcuffed my hands behind my back and had my key in hand. these are police grade no chain, no safety cuffs. I've been able to get out before, but its tough. Well, I'm in writhing pleasure with the vibe, and I dropped the keys into the crack between to sections of couch! I was like "oh...shit" and I tried frantically to reach them. No luck. I was at the mercy of my vibrator and kept cumming and cumming! It was  torture! Suddenly my tablet starts ringing. My girlfriend! I couldnt skype like this. So I ignored. My room mate wasnt due home for 3 hours. I was nearly in tears. I rolled off the couch and tried to reach the key, still couldnt reach it! So there I was tied up, on the floor squirming in pleasure/pain. I think I may have passed out at some point, because suddenly there was only 30 minutes left. Monique doesnt know about my fetishes so it would be really embarassing to be caught like that. The vibe batteries must have been dying because through my scrambled brain I knew I had to reach the key, but it was no use. Monique came home, saw me there on the floor, nearlh naked and tied up. I was so embarassed!  I barely was able to mutter "help" and tell her where the key was. She unlocked me and then turned around and went to her room. I turned off the vibe and went to get dressed. My god, my wrists are so bruised, just like my ego!
